Proust on Music and that phrase of Vinteuil's

From Swann's Way, the original translation:

He knew that his memory of the piano falsified still further the perspective in which he saw the music, that the field open to the musician is not a miserable stave of seven notes, but an immeasurable keyboard (still, almost all of it, unknown), on which, here and there only, separated by the gross darkness of its unexplored tracts, some few among the millions of keys, keys of tenderness, of passion, of courage, of serenity, which compose it, each one differing from all the rest as one universe differs from another, have been discovered by certain great artists who do us the service, when they awaken in us the emotion corresponding to the theme which they have found, of shewing us what richness, what variety lies hidden, unknown to us, in that great black impenetrable night, discouraging exploration, of our soul, which we have been content to regard as valueless and waste and void. Vinteuil had been one of those musicians. In his little phrase, albeit it presented to the mind's eye a clouded surface, there was contained, one felt, a matter so consistent, so explicit, to which the phrase gave so new, so original a force, that those who had once heard it preserved the memory of it in the treasure-chamber of their minds. Swann would repair to it as to a conception of love and happiness, of which at once he knew as well in what respects it was peculiar as he would know of the Princesse de Clèves, or of René, should either of those titles occur to him. Even when he was not thinking of the little phrase, it existed, latent, in his mind, in the same way as certain other conceptions without material equivalent, such as our notions of light, of sound, of perspective, of bodily desire, the rich possessions wherewith our inner temple is diversified and adorned. Perhaps we shall lose them, perhaps they will be obliterated, if we return to nothing in the dust. But so long as we are alive, we can no more bring ourselves to a state in which we shall not have known them than we can with regard to any material object, than we can, for example, doubt the luminosity of a lamp that has just been lighted, in view of the changed aspect of everything in the room, from which has vanished even the memory of the darkness. In that way Vinteuil's phrase, like some theme, say, in Tristan, which represents to us also a certain acquisition of sentiment, has espoused our mortal state, had endued a vesture of humanity that was affecting enough. Its destiny was linked, for the future, with that of the human soul, of which it was one of the special, the most distinctive ornaments. Perhaps it is not-being that is the true state, and all our dream of life is without existence; but, if so, we feel that it must be that these phrases of music, these conceptions which exist in relation to our dream, are nothing either. We shall perish, but we have for our hostages these divine captives who shall follow and share our fate. And death in their company is something less bitter, less inglorious, perhaps even less certain.

So Swann was not mistaken in believing that the phrase of the sonata did, really, exist. Human as it was from this point of view, it belonged, none the less, to an order of supernatural creatures whom we have never seen, but whom, in spite of that, we recognise and acclaim with rapture when some explorer of the unseen contrives to coax one forth, to bring it down from that divine world to which he has access to shine for a brief moment in the firmament of ours. This was what Vinteuil had done for the little phrase. Swann felt that the composer had been content (with the musical instruments at his disposal) to draw aside its veil, to make it visible, following and respecting its outlines with a hand so loving, so prudent, so delicate and so sure, that the sound altered at every moment, blunting itself to indicate a shadow, springing back into life when it must follow the curve of some more bold projection. And one proof that Swann was not mistaken when he believed in the real existence of this phrase, was that anyone with an ear at all delicate for music would at once have detected the imposture had Vinteuil, endowed with less power to see and to render its forms, sought to dissemble (by adding a line, here and there, of his own invention) the dimness of his vision or the feebleness of his hand.
